Epoxy resin is an important organic synthetic material composed of epoxy groups and benzene or aliphatic rings. It has good corrosion resistance, mechanical properties, and chemical stability, and is widely used in fields such as coatings, adhesives, and electronic packaging. The preparation methods of epoxy resin mainly include oxidation-reduction method, epoxy compound method, and photopolymerization method. Among them, oxidation-reduction method is a commonly used method, and its main steps include: selecting appropriate epoxy groups and benzene or aliphatic rings, and generating epoxy resin through oxidation-reduction reaction. In addition, the performance and application of epoxy resin are also influenced by factors such as its molecular structure, curing conditions, and additives.
